qimgv VS KittehPlayer

about this time, i am a little more than intrigued and a bit confused. i use my image viewing program qimgv (github) by typing qimvg 87956_60.png and was shown a photograph of a man seemingly turning his head to look at me.

qimgv - Image viewer. Fast, easy to use. Optional video support. Very powerful, qt app, best for me.

I use qimgv, It's mostly frameless (It only has a window bar), supports going left and right through images, even sorted by date and even on a directory with 80k+ files in it. It also has some very useful features in the right-click menu and also has a folder view and is highly customizable.

I don't know exactly what you mean by "nothing", but JPEG XL is already supported for almost all image viewers on Linux installing the libjxl plugin system wide, and on Windows good image viewers like XnView, IrfanView e my personal favorite qimgv, and all most used browsers already supports jpeg xl, however is not enable by default and you need to enable it in the hide settings, but I agree that you probably will not want to use jxl if you are sharing images to other people all the time on different platforms and can't bother to decode before doing, or are using it on other devices that don't use a desktop OS, that is way I only recommend it to people that like "bleeding edge" stuff, my first recommendation is still use something like pingo if the original format is a must.

My personal favorite is qimgv. It even supports videos with an additional download, which is awesome for me.

qimgv can also save AVIF

7zip, Rufus, BleachBit, Bulk Crap Uninstaller, SpeedCrunch, ShareX, Keypirinha, Everything, OBS, qimgv and of course Nextcloud are all the essential free/open source software I need.

Add mpv for better hwdecode support. For loop behaviour, qtmultimedia is set to keep last frame, mpv is default setting. For vo=libmpv, see this issue
